Feedback / Testimonials

Irene Hope, Falkirk said on 27/10/2020:
Mark replaced my old Central Heating Boiler at a very reasonable price. He was very kind, reorganised all the piping and other equipment so that I had more room, was extremely clean and tidy, making sure he didn’t leave any wet footprints, explained everything in a way that I understood, and even phoned me a couple days later to make sure I was happy with everything. I would certainly recommend him and will be using him in the future.

Ivy Blair, Grangemouth said on 23/09/2020:
Mark did a great job installing boiler – professional and took time to explain everything – efficient and cleaned up afterwards. Great service at a very good price. Thanks.

Margaret Laird, Grangemouth said on 17/07/2020:
Mark Dennington was recommended to me by a friend. I needed a new boiler and larger radiator in the lounge. I got another quote from another company, as well as from Mark.  On meeting him, I felt immediately assured of his excellent knowledge and ability. The work is now completed, and I could not be happier. Nothing was any bother to him. I think he goes above and beyond to give a very high standard of workmanship. I would highly recommend him to anyone, needing any plumbing work carried out.  I would not hesitate to engage him again.

Mary, Bo’ness said on 09/07/2020:
Excellent efficient service from Mark today. He was friendly and fixed my gas hob with no mess or problems. Cost was also reasonable. I would highly recommend him.

JH, Falkirk said on 18/03/2020:
Mark recently replaced a hot water cylinder for me. From the outset he was impressive….courteous, punctual and knowledgeable. A complete professional , I would highly recommend him and would definitely use his services again.

Christine Stewart, Larbert said on 20/02/2020:
I got Mark’s details via Trustys and he has been out fixing my boiler.  He has it all fired up and back working again.  He has been a great help to me and he is a very nice chap.

Val, Polmont said on 09/02/2020:
Mark fitted two new radiators and carried out the boiler service.  He had fitted the boiler last year and did the work to a very high standard.  He pays attention to detail and does the work for a reasonable price.  Because of a family crisis, I had to leave the house, but Mark kept me informed of progress by phone and took the time to fix an unexpected problem.  I have recommended Mark to family and friends.

Chris, Polmont said on 08/02/2020:
Mark really got us out of a tight spot, a week before we were due to move house our boiler packed in, thankfully he was able to move some things around and fit us in on very short notice.  He managed to get the old boiler removed and the new boiler fitted and working all within one day.  He came back the next day to flush the system.  Mark did an absolutely fantastic job getting the boiler up and running.  He kept us informed all the way through and was extremely punctual. When we moved into our new house Mark filled the system and sorted out the problems we had with the central heating.  Mark really is fantastic, I would highly recommend him for any of your Plumbing / Heating needs. I plan to use him again in future. Thanks Mark

F Thornton, Old Plean said on 11/11/2019:
Mark recently carried out work on our central heating system.  He did a fantastic job, was a punctual, neat and tidy tradesman who I would thoroughly recommend to anyone looking for a plumber. We will definitely use him again.

Allyson, Larbert said on 15/09/2019:
Quick and efficient installation of new boiler and replacement of damaged flue.  Very responsive to contacts and helpful in emergency. Work left tidy and clean. Strongly recommended.

Scott Camilin, Rumford said on 11/09/2019:
Mark Dennington fitted a new boiler a few weeks ago and I’m very happy with the job he’s done. This was a big and expensive undertaking but done for a fair price.  Mark worked tirelessly to resolve issues arising from work not done properly when our house was built some 20 years ago.  He kept us updated at every stage and made sure all our gas appliances continued to work properly after he finished the installation.  We now have lots of hot water and powerful showers!

Suzy, Stenhousemuir said on 14/07/2019:
Mark was brilliant, asked for 4 new radiators to be fitted but when he started removing old ones discovered system was badly needing flushed, so a 1 day job turned into 3 day job.   Mark worked so hard and returned several times so that job would be complete for new carpets being fitted.

Marc, Polmont said on 30/04/2019:
We called Mark about a problem with our boiler.  He came out exactly when he said he would and diagnosed the issue quickly.  He gave us a range of options to solve it and we opted to install a new boiler.  Mark fitted the new boiler for us to a high standard.  From my first call to the final visit I was impressed with Mark’s professionalism – he arrived when he said he would, kept us updated when he said he would and left the work area tidier than when he started!  We also called him afterwards for an unrelated leak and he came out to us very quickly, was very helpful and fixed the issue. I will be using Mark for all my plumbing requirements in the future and would have no hesitation in recommending him to others.

Mr & Mrs Curtis, Bo’ness said on 09/04/2019:
Matthew and Mark did a great job on a complete bathroom refurbishment, including the unexpected rebuilding of a wobbly partition wall into a bedroom.  We would highly recommend their attention to detail, transparency on costs, tidiness and flexibility in helping to meet our requirements.  Matthew’s communication from start to finish was excellent.  He arranged electricians, plasterers and tilers who together completed all work to a very high standard.  We have a new bathroom that has exceeded our expectations and we really appreciate the hard work that Matthew and his team put in to make this happen.

Jenn, Polmont said on 28/03/2019:
 Mark and Matthew have recently completed a bathroom refit for us.  They were incredibly helpful, and nothing was too much bother – especially when we came up against mishaps (of both our own doing and suppliers ceasing trading!).  They were patient and friendly and always available to answer calls and queries.  More than happy to highly recommend them.

Gaynor Kelly, Bo’ness said on 12/03/2019:
We required a new boiler to be installed as well as other additional plumbing work.  We were really impressed with Mark’s work, his commitment, tidiness and also his customer service was second to none.  We would recommend Plumbsure to anyone, and we will definitely call on Mark again in the future.

Mhairi, Bonnybridge said on 20/02/2019:
Mark has done a fantastic job for me.  He has replaced my old boiler with a fab new combi one, and other little plumbing emergencies.  Professional and efficient throughout, the work was carried out thoroughly and swiftly.  Clean and tidy work, I would recommend Mark to anyone. Thanks Mark

Lynn McLellan said on 20/02/2019:
Mark (Plumbsure) & Matthew (Premier) came to the rescue when another plumber had left us in the lurch.  The guys were great, they came in, assessed the job and replaced a double shower for us.  A 16-week insurance nightmare resolved in two days.  Would highly recommend both businesses.

Tracey Elfendi, Denny said on 06/02/2019:
Mark yet again to the rescue!!! Nothing is ever too much trouble for him.    I’ve lost count over the years how often I’ve called him.  Always the same great service! One of my pipes had a pinhole in it and was leaking down to the neighbour.  He was there asap and he always keeps in touch and lets you know what’s happening! Highly recommended as always.

LH, Grangemouth said on 01/02/2019:
Contacted Mark late afternoon when a boiler wasn’t working.  Despite him being very busy and already scheduled to work till 2000, Mark took the time to listen to my problems and assured me that he would attend.   True to his word, he attended and quickly diagnosed and fixed the problem.   Top class customer service from a top  class engineer.

Val Stevenson, Polmont said on 21/12/2018:
Mark has just completed installing a new boiler in my house. He gave good advice about the different boilers available, allowing me to make an informed choice. He is very pleasant and knowledgeable. I would highly recommend him for the standard of his work.

Linda Hardie, Grangemouth said on 19/11/2018:
Went on Trustys to find a plumber and got Mr Mark Dennington of Plumbsure.  Great job, excellent service, no mess to clear up and would highly recommend him.

Emma, Grangemouth said on 11/11/2018:
Mark has carried out work for us in the past and I had no hesitation in asking him when we were looking for someone to put a new bathroom in for us.   He took over the job for us, taking on board any workarounds we presented him with and rescheduling to suit our needs with no problem.   He takes pride in his work, I felt I could trust him, and he has a good team around him.

Liz, Polmont said on 06/11/2018:
Mark has just installed an additional radiator for us in the utility room. Excellent job. Can highly recommend. Will use Mark again in the future.

John & Sandra, Brightons said on 02/11/2018:
We called Mark out to replace the control panel for our boiler.  He checked everything thoroughly and once he’d sourced the part he phoned with a price.  Came when he said he would and fixed the part.  Very pleasant, knowledgeable man.  Would recommend and use again.

Morag Cantwell, Stenhousemuir said on22/10/2018:
Mark replaced my central heating boiler.  He was punctual, very pleasant and made sure he covered all my floors.  He came back to flush the system and also said we would get a free service in a years’ time.  I would have no hesitation in recommending him for any similar work.

Mrs Lammie, Grangemouth said  on 10/10/2018:
Had to call Mark to fit a bracket on to the flue in the loft. A small job but carried out promptly and efficiently by Mark at a very good price. A pleasant young man  who is very knowledgeable. Highly recommend him.

Mr Dawson, Grangemouth said on 08/08/2018:
Mark done an absolutely fantastic job for me in getting my boiler up and running.  The original engineer I phoned came to my house three times and couldn’t fix it and claimed that the part was obsolete.  Another engineer came and promised me the earth and said he would get the part for me no problem, only to let me down.   I then phoned Mark who sourced the part and solved my problem.  Mark is very good and he did everything he said he would and the price was fantastic. Mark is definitely the man and a lot better than the other two.

Jim Laing, Polmont said on 03/08/2018:
As we had a problem with our Combi boiler not igniting I needed someone knowledgeable and trustworthy to investigate. Mark Dennington from Plumbsure took the time to research the problem rather than simply replacing the first part that “might” have been the culprit. This research paid off and the boiler was soon working again. Mark was happy to come at a time that suited me, and he cannot be faulted. Reasonable rates, no mess, happy to explain what he was doing and what he reckoned the issue was. If I need a plumber and / or boiler engineer in the future, he is definitely the right man. People are quick to complain and less keen to praise, so when someone deserves that praise they should get it. Thanks again Mark.

Jackie McPhail, Falkirk said on 08/07/2018:
I have been meaning to post about Plumbsure, I have now had Mark out to do work in 4 different houses, he is such a lovely guy, he now feels like family but better than family, he is a fabulous tradesman.  He will go the extra mile to get the job done perfectly.  I would recommend him to anyone.

Alison Farquhar, Grangemouth said on 08/07/2018:
Great service.Willing to discuss all options and work it out. Felt completely reliable and trustworthy. Brilliant tidy job done. Hassle free visit. Totally recommend. Thank you.

Donald MacDonald, Bo’ness said on 02/07/2018: Mark Dennington of Plumbsure did some work for us recently in connection with the replacement of a faulty cistern and flush pipe, the installation of a new shower, and the replacement of kitchen and bathroom taps. We found Mark to be knowledgeable, thorough, adaptable and competent, with a friendly, pleasant manner. I fully intend to employ Mark for any future plumbing jobs that require to be done around the house.

Mr Gillespie, Falkirk said on 28/03/2018:
I highly recommend Mark from Plumbsure for his excellent quality of work.   Mark created an en suite for me from scratch, were there had been no previous plumbing hot/cold water or waste pipes.  After numerous plumbers not turning up or providing quotes.   Mark arrived quickly, sent a quote, carried out the work to a very high standard and with great communication throughout.  I would not hesitate to call Plumbsure for any future work and would happily endorse Mark.
